HEAT CONSERVER AND DISPENSER.

Application filed November 23, 1925. Serial No. 70,886.

This invention relates in general to heating appliances and moreparticularly to a heat conserver and dispenser to operate in conjunctionwith a suitable source of heat for economizing in the distribution ofthe heat from the source and for making such distribution moderate.

lVhile the invention broadly comprehends its use for the economical andcomfortable heating of dwellings and other places where permanentinstallations of the equipment may be made, it will suflice in thepresent description to refer to one particular embodiment of theinvention where the general principle involved is shown applied to asmall, portable heater unit for occasional use.

In the accompanying drawing illustrating the invention,

Fig. 1 is a vertical, longitudinal section through a heat conserving anddispensing device shown placed on an electric plate or other suitableheating source;

Fig. 2 is a perspective view of my improved device.

3 The present embodiment of my invention comprises a box-like container5 of metal or any suitable material which is open at op posite ends andreceives a heat absorbing body 6. The body 6 consists of a zigzag striof sheet metal bent, as shown at 7 and 8 with the contiguous plates orlaminae 9 closely spaced and in mutually divergent and convergentrelation. The bends 7 and 8 are transverse with relation to the openends of the box, as illustrated, with the bends 7 flush with the end ofthe box at the bottom open end lO thereof. This brings these points ofthe absorbing body 6 in intimate contact with the heating source 11which, as stated above, is an electric plate but may be any othersuitable or convenient heating element. The bends 8 protrude slightlyfrom the open top of the box, as illustrated, thereby leaving draftopenings or vents 12 at opposite sides of the box. The opposite ends ofthe zigzag strip are bent as shown at 13 to overlie the upper edges ofthe box and support the body 6 therein.

The unit illustrated is merely for the purposes of the presentdescription to convey a general understanding of the invention and theprinciple involved. Consequently, it should be understood that nolimitation as to size or the thicknesses of the parts is intended to beconveyed. In the use of the device, the same may be permanently attachedover an electric plate by lugs 14 on a base 15 or the same may beremovable for use wherever desired. In operation, the heat absorbing andstorage body 6 can be heated up in the course of a few seconds dependingon the size of the unit in hand and on the thickness of the metal used.After removal from the heating source or by shutting off the currentsupplied to the electric plate, in the present case, the body 6 will befound to hold heat for a considerable time, the heat dispensed beingmoderate and comfortable and not intense and local as in the case ofportable heaters commonly used. The laminae 9 reflect and radiate heatfrom one to another due to their arrangement and close relation andbecause-of the fact that direct draft is kept therefrom by the box 5serving as a shield therefor. The heating of the body from the sourceoccurs rapidly by virtue of the direct conduction resulting from contactwith the source at the bends by radiation in which-the vents 12 permitof the dispensing of heat from within the container from the spacesotherwise closed by the zigzag strip. There is, of course, aconsiderable saving in expense by utilizing my invention and Icontemplate its use where the source of heat may be in intermittentoperation for which purposes electrical appliances are. of course, mostsuitable. In this connection, thermostatic temperature controllin meansmay be used for closing and opening the circuit for the electric heatingunit.

I claim: I

1. In a heat conserver and dispenser, a box-like container having a heatoutlet opening, and a heat absorblng body consisting of a zigzag stripof sheet metal placed inside the box with the planes of the bendstherein transverse to the heat opening, the bends at said opening havingdraft openings, and the other bends being in intimate heatreceivingrelation to a heating source.

r. The dispensing of the heat is of course the other bends to transferheat to the radiating element, the first mentioned bends in saidradiator element being open to the atmosphere at the ends thereof.

In Witness of the foregoing I aflix my signature. I I V I N OTTOLUNDELL.
